This is interesting. I have to admit I haven't thought much about this at all. Like what the ideal abstraction is?, how to expose it etc?.. I see this is a dedicated router which seems reasonable, but I'm going to need some more feedback to know what expectations are here. I don't know if @nksaraf has any thoughts. Might look at bringing this in as an experimental feature at first given us trying to lock down for 1.0.

Yes, it definitely is an experimental feature! I just wanted to allow people to start playing with it as soon as possible, since WebSockets are an important piece of modern web apps.

CrossWS seems very promising and runtime agnostic, similar to Nitro.
